The purpose of this study was to investigate the range of condylar movement of children with young permanent dentition. Materials included 33 roentgenograms of 4 serial projections of TMJ by modified transcranial projection with Accurad 100. Four serial projections were taken in the centric occlusion, rest position, 1 inch open, and maximum open position. The results obtained from this study were as follows. 1. The condyle was located anteriorly in articular fossa at centric occlusion. 2. The condyle was moved forwardly and downwardly during mandibular movement from centric occlusion to maximum open position. 3. The pattern of condylar movement was similar in both sexes, but there were no sex differences in distance of condylar movement.

A draconematid nematode species, Dracograllus filipjevi Allen and Noffsinger, 1978, is described from the washings of shallow littoral coralline algae at Guryongpo in the eastern coast of Korea. This species is recognized by the following characteristics: larger body size, number of posterior sublateral adhesion tubes (9 in male and 12-13 in female) and subventral adhesion tubes (8-9 in male and 9-10 in female), the absence of cephalic acanthiform setae on rostrum, the presence of longitudinally areolated body cuticle with dot-like punctations, the presence of some cuticular collar in swollen pharyngeal region, the shape of amphidial fovea (large, elongate, and loop-shaped in both sexes), the absence of preanal corniform setae, and the absence of lateral differentiation on narrow body region. Morphological features of the species using differential interference contrast photomicrographs are described in detail in the present work. The is the first report of D. filipjevi in Korea.

As a means of achieving fashion technology and scientification, this research on the standardization proposals of body type research methods has the following conclusions: 1. As human body displays different characteristics according to races, regions, sexes, and ages, clothing products (unlike other industrial goods) cannot be subject to global standardization. As a result, clothing size standardization can be desirably regionalized, for example, as Asian, European countries, etc. 2. In order to share human-body-concerned information among nations, programs for raw data exchange need to be urgently developed. 3. Top priority is databasing all raw data at home and abroad. 4. So that the findings of body type research can be practically applied to the concerned industry, industry-academy cooperation and information exchange are a must. While researchers have to heighten the precision of their studies, industrial partners ought to focus on the invaluable importance of academic research. 5. The scientific body type analysis, the basis of fashion technology, as well as the development of its application technology and software are ultimately and urgently required.

The aim of this study was to describe growth patterns of mice using Gompertz model. Two distinct types of mice, laboratory mouse $CF_{\sharp1}$ (Mus musculus domesticus) and Yonakuni wild mouse (Yk, Mus musculus molossinus yonakuni) were used. From all possible crosses, there were two parental types and two reciprocal $F_1$ crosses obtained. Individual body weights were measured weekly from birth to ten weeks of age on 321 mice. Standardization to six mice was conducted and only first litters were used. Growth curve parameters were estimated to fit growth data. The results showed that growth among genetic groups were significantly different (p < 0.05) for both sexes, in which parental type of $CF_{\sharp1}$ and Yk had the highest and the smallest values, respectively. Meanwhile, reciprocal $F_1$ crosses were intermediate between parental types. It was concluded that Gompertz model provided and excellent fit for the growth data with a high coefficient determination $(R^2 = 0.999)$.

A study was carried out to investigate the effect of palm oil supplementation on the growth, carcass composition and fatty acid distributions of the broilers fed isonitrogenous and isocaloric diets. This study showed that palm oil supplementation increased feed consumption, weight gain and nitrogen intake. Feed conversion improved at higher fat inclusions, but not significant. Male birds consumed significantly more feed than females resulting in significant increase in energy consumption and weight gain. Increaseing fat content in the ME:P constant diet did not produce significant difference in the fat content of the chicken. Fatty acids content of the diet exert varying effects of the composition and distribution of fatty acids in muscles of the chicken. The fatty acids found in larger amount in the breast and thigh muscles were palmitic, oleic and linoleic. The fatty acids of the breast and thigh muscles were found to correspond the fatty acids of the diets. There were no differences in the fatty acids distribution patterns between the sexes.

Endocrine disruption in crucian carp (Carassius auratus) living in the branch of Han River were examined. Vitellogenin level in plasma was measured using ELISA system and aromatase mRNA level in brain was observed using RT-PCR technique. In all female fish, vitellogenin levels were in the range of 20∼40 $\mu\textrm{g}$/ml and aromatase mRNA expression could be detected on the agarose gel after RT-PCR. However, in case of males, vitellogenin level was elevated in only one fish, while vitellogenin was hardly detected in others. Aromatase was expressed in all males although the levels were relatively lower than the level in female fish. Testis-ova and any other histological changes of reproductive organ were not shown in both sexes.

The status of the nutrient supplement usage of the adults in Seoul was investigated. One thousand two hundred adults from various age groups were chosen as the subject of this study. Data of this study were obtained by means of self administered questionnaire for demog-raphic characteristics(sex,age,edcation,income,occupation) and behavioral characteristics (reason for using nutrient supplement or not using,exercise,drinking & smoking). The overall response rate was 85%(n=1031). As a result, a substantial percentage(40%) of the subjects were used some kinds of nutrient supplement. The higher the age, educational level, and family income were, the higher the percentage of nutrient supplement usage was. But there was not the significant difference between sexes(38% in men vs 34% in women). And supple-ment usage was higher in the thin and obese groups than the average weight groups. Majority of subjects indicated that the information source of supplement was "Family/Friends" or "Phy-sician/Pharmacist". KEY WORDS: supplement usage vitamin/mineral supplement health food.

To assess the relationship between angiotensin-converting enzyme (ACE) gene polymorphism and myocardial infarction in Koreans, we recruited 112 healthy, unrelated subjects (mean age 53.4 years) and 104 myocardial infarction survivors (mean age 54.2 years) of both sexes. An insertion/deletion (I/D) polymorphism of the ACE gene was typed by polymerase chain reaction. The I allelic frequency of ACE gene in Korean subjects was irrelavant to myocardial infarction (patients, 65 control subjects 66%), as was true with the D allele. When compared with other populations, the frequency of D allele in Koreans (0.34) was lower than that in Caucasians, and was close to that of other Oriental populations. The data suggest that the ACE gene polymorphism is not an independent genetic risk factor for myocardial infarction in Koreans.

Single and 28-day repeated dose toxicity studies of botulinum toxin type A(BTA) were carried out in ICR mice and SD rats. respectively. In the single dose toxicity study. BTA was injected intraperitoneally to male and female mice at a single dose of 40, 59, 89, 133 and 200 ng/kg. All animals died from 59 ng/kg. Some clinical signs were observed in most of both sexes from 59 ng/kg, but no signs were seen in all animals at 40 ng/kg. (omitted)

The serum alkaline phosphatase activity was determined with 64 Korean cattles in different sexe and age groups, using p-nitrophenylphosphate as the substrate. The results obtained were as follows: 1. The mean value of serum alkaline phosphatase activity in Korean cattle was $1.78{\pm}0.21$ Bessey-Lowry units/ml, and $1.71{\pm}0.21$ units/ml. in female and $1.86{\pm}0.21$ units/ml. in male, respectively. 2. The serum alkaline phosphatase activity decreased with age from 4 years group. 3. No statistical significance was recognized among the sexes, but difference among the age groups was found to be highly significant.
